The megalomaniacal dictator of North Korea, Kim Jong-un, was born today either in 1982, 1983, or 1984, depending on whether you take North Korean, South Korean, or American records as the most reliable.

They can reveal, for example, that Kim Jong Un was born in 1984 – not 1982 or 1983, as has been widely believed. The reason they’re certain? It was the same year that their first son was born. “He and my son were playmates from birth. I changed both of their diapers”, Ko said with a laugh.

Kim likes to celebrate with extravagant public celebrations, like basketball games, using money that could feed the starving populace. Here’s Dennis Rodman singing “Happy Birthday” to him in 2014:

Also on this day a few years before Kim’s birth, China’s long-time diplomat and official Zhou En-lai, who was instrumental in shepherding China’s opening with the United States, died in 1976. Zhou served as Premier of the PRC from its founding until the day of his death. He negotiated and did rice wine shots with Henry Kissinger and Richard Nixon.
